Take some bills out of your wallet. Read the signatures. What do you have?

I've got a couple of Henry Paulsons, some Robert Kimmitts and a Stuart Levey. But now, the currency of the greatest nation on Earth will carry a scribble that has been variously described as curly fries, a phone cord, a bendy straw or simply the "Boing!" sign from a comic strip.

Slinky as signature: What does it mean?

I know a guy who is a great artist, and his signature is mainly a straight line interrupted by a bump in the middle, which could have been caused by someone accidentally hitting the table. But he is an artist and can do what he wants.

I also know people who have had their 1040 tax returns rejected by the IRS for a boing-style signature.

Is it possible that our Treasury secretary could have his tax returns go awry because of his penmanship? Could the Chinese start rejecting the almighty dollar because they think the boing looks too weird? Or could his signature mean something else in Chinese, like "We will bury you" or "This is Monopoly money"?

Jack Lew is a Harvard-Georgetown, really smart type of guy, and God knows we probably owe him a lot. He's been a good chief of staff in just keeping the birthers out of the Oval Office so Obama could govern.

But please, Mr. Lew, retire the boing. After all, "Lew" is only three letters long.
